I think that Brian and I have figured out how to build the prototype that will tell me whether or not the idea of clad SS will be a good roasting environment… and for a relatively low amount, be able to test whether I should be buying 1/2, 1/4, or 3/4″ thick outer material. I’m pretty confident that the Stainless should be as thin as I can get it so that it acts as only as a surface, and plays into the thermal properties of the drum wall as little as possible.
There’s no question that having the drum constructed by a good machine shop is the more better of options, but for prototyping this entire idea, I can’t justify the cost without knowing if it is going to work.
Anyway, I have to hand it to Brian, he knows how to build things, and I believe that he is right—that the variation between the way a machinist would create this drum and the way we will, will be minimal and enough that we will be able to know whether it is worth it or not. If it is, and I know how thick the outer wall needs to be, then I’ll think about having it machined.
